The AIM-listed investment group, which has an interest in the NTI through a stake in African Tantalum Limited (Aftan), said 165 core samples from Homestead would be prepared for assay by geochemistry analysis firm ALS.
Kazera added that the channel sampling at Homestead would aim to define Lithium and Tantalum mineralisation in the area as well as its grade.
Aftan had also sub-contracted a third-party earthmoving firm to clear all drilling tracks in advance of the drills arrival, the company said.
Meanwhile, Kazera said Aftan would be meeting with bidders involved in the tender of the Orange River pipeline to review their technical proposals following the receipt of a water license to acquire water from the river in March.
Seven companies are currently bidding for the license, and the company is seeking to reduce these to a short list following proposal review.
